Removal

•	MCU is integrated with HPCU. Therefore, to install / remove the MCU, follow the procedure for installing / removing the HPCU. (Refer to Hybrid Control System - "HPCU (Hybrid Power Control Unit)".)

•	You need to perform resolver compensation whenever the engine, HPCU, drive motor, or starter generator (HSG) is replaced, removed, or reinstalled. Perform compensation according to the GDS motor / HSG resolver compensation procedure shown below.

GDS Motor/HSG Resolver Compensation Procedure
